THE

IMPROVED STRIKE FOR DOOR-LOCKS.

Specification forming part of Letters Patent No. 38,203, dated April 14,1863.

To all whom it may concern Be it known that I, JAMES E. TERRY, ofPhiladelphia, in the county ot' Philadelphia and State of Pennsylvania,have invented a new and useful Improvement in Strikes for Door-Locks;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the `accompanyingdrawings, making apartof this specification, in which- Figure l is afront or face view of my invention applied to a door-frame, the lock anda portion of the door being shown in red; Fig. 2, the same view as Fig.l, with the eX- ception that the invention is used with a door whichswings in an opposite direction to that of Fig. 1; Fig. 3, a detachedside view of my invention.

Similar letters ot .reference indicate corresponding parts in theseveral figures.

The object of this invention is to obtain a strike for door-locks whichwill be capable ot' being applied, without being inverted or re versedin position, to the frame of either a right or left hand door. Theinvention is designed to be used with what is generally known as thecarpenter-lock,7 or those which have a latch or risingand-falling bolt.

The invention consists in forming the strike with a centralpartition-plate and having an opening to receive the latch at each sideof said partitionplate in the Jr'ace or front plate of the strike, withan inclined projection below each latch-opening, all being arranged insuch a manner that the desired end is attained.

To enable those skilled in the art to fully understand and construct myinvention, Iwill proceed vto describe it.

A represents the strike, which may be cast in one piece, of anysuitable. metal, and is formed of a face or front plate, a, having twoopenings, b b, in it at each side and in line with each other, as shownclearly in Figs. 1 and 2. At the inner side of this face or front plate,c, there is a central partition-plate, c, which may extend the wholelength of a, terminating at each end in a semicircular or arched rib, d,the width of which is equall to I the plate a. These ribs d serve tostrengthen the strike, and afford a good bearing for the same whenapplied to the frame or easing of the door, the strike being secured tothe frame or casing by means of screws passing through the face orfrontplate,a. The two latch-openings b b are divided by a plate, e,which extends down to an inclined projection, f, the upper edge of whichis in line or terminates with the lower edges of the latch-openings b b.By this arrangement it will be seen that what may be termed a doublestrike77 is -obtained, as either part or side may be usedthat is to say,either latch opening b placed adjoining the lock, according to which waythe door swings. This will be fully understood by referring to Figs. land 2, in which the strike is shown applied in one to the right and inthe other to a left hand door, a portion of a door and its case or framebeing shown in red. It will also be seen that in order to apply thestrike to either door. the former does not require to be invertedthelock requires to be inverted, but not the strike. The latter hashitherto been made with two openings at one side-one near the upper andthe other near the lower end-so that by inverting the strike, as well asthe lock, the former could be applied to either a right or left handdoor. Strikes formed in that way, however, do not present as neat anappearance as the withindescribed invention, as the unoccupied openingat the lower part of the strike destroys the uniformity of the parts,and gives an unsightly appearance to the same.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

A strike provided with two latchopenings, b b, side by side, an inclinedprojection,f, and a central partition-plate, c, all arrangedsubstantially as and for the purpose herein set forth.
